De-superheater for evaporative air conditioning

Abstract

An evaporative condensing air conditioning system employing a de-superheater and mist eliminator located between the air fan on an evaporative cooler and a spray tree that delivers water 20 as a coolant on the exterior surfaces of a condenser coil. The de-superheater receives superheated coolant gas from the compressor of the air conditioning system where air traveling on the outside of the de-superheater coil removes heat from the coolant gas located within the de-superheater coil to the point where the coolant is still a gas but is no longer superheated. The coolant gas then exits the de-superheater and flows into the evaporatively cooled condenser coil where the coolant is further cooled and condenses into a liquid before finishing the air conditioning circuit by consecutively moving through an optional coolant receiving chamber, a thermal expansion valve, an evaporator, and returning to the compressor.

What is claimed is:  
     
       1. A de-superheater for an evaporative condensing air conditioning system comprising: 
       an air cooled de-superheater coil, said de-superheater coil connected to and receiving superheated coolant gas from a compressor of an evaporative condensing air conditioning system, and said de-superheater coil provided with one connection to and supplying completely de-superheated coolant gas to an evaporatively cooled condenser coil of the evaporative condensing air conditioning system.  
     
     
       2. A de-superheater for an evaporative condensing air conditioning system according to  claim 1  further comprising: 
       a mist eliminator located between the de-superheater coil and a spray tree of the evaporative condensing air conditioning system to prevent water droplets from the spray tree from reaching the de-superheater coil.  
     
     
       3. An evaporative condensing air conditioning system with de-superheater according to  claim 1  further comprising: 
       said condenser coil connected to and supplying liquid coolant gas to a thermal expansion valve, said thermal expansion valve connected to and supplying coolant gas to an evaporator, and said evaporator connected to and supplying coolant gas to said compressor.  
     
     
       4. An evaporative condensing air conditioning system with de-superheater according to  claim 3  further comprising: 
       a mist eliminator located between the de-superheater coil and a spray tree of the evaporative condensing air conditioning system to prevent water droplets from the spray tree from reaching the de-superheater coil.  
     
     
       5. An evaporative condensing air conditioning system with de-superheater according to  claim 1  further comprising: 
       a common air supply passing through both the evaporatively cooled condenser coil and the de-superheater coil.  
     
     
       6. An evaporative condensing air conditioning system with de-superheater according to  claim 5  further comprising: 
       a mist eliminator located between the de-superheater coil and a spray tree of the evaporative condensing air conditioning system to prevent water droplets from the spray tree from reaching the de-superheater coil.
